Answer 1

child_mc.addEventListener(MouseEvent.CLICK, onParentFunction)

onParentFunction(e:MouseEvent)
{
  parentFunction();
}

Whenever you need to call a function on a parent class then use events. If you were not clicking on a child you can do something similar by dispatching an event. Simply:

In child_MC

dispatchEvent(new Event("SOME_EVENT"));

Parent

child_mc.addEventListener("SOME_EVENT",onSomeEvent);

function onSomeEvent(e:Event):void
{

}
